Let’s do our best. Great advice and we should strive to perform at all times.
Big picture, however, I say let’s working on who we are, and how we impact others with the totality of who we are and how we impact them.
Step one is to gain awareness of who you are and what makes you tick. Your bottom line internal self is always there, work to know and understand it and then you can make improvements if you’d like, or simply accept and be great.
